/*
 * Phosphor's base .ph-duotone class doesn't set display:inline-block.
 * Without it the :after pseudo-element's margin-left:-1em (used to
 * overlap the two duotone glyphs) doesn't work reliably in all
 * layout contexts, causing icons to render as two separate characters
 * or show nothing at all. This is especially pronounced for icons inside
 * dynamically-created elements (e.g. login modals created via innerHTML)
 * where pseudo-elements may not receive layout until a repaint.
